The pressure washing procedure is also known as high pressure washing, steam cleaning, water blasting, house washing or power washing. The procedure involves the thrust of up to 220 degrees of hot water from a 13 horse power engine. Hot and strong enough to remove stubborn stains such as chewing gum, oil, rust, paint, mildew, algae, mold and other unsightly stains. If you have green algae or mold/mildew on concrete, stucco, aggregate, flagstone, gunnite or brick surfaces it's time to have them cleaned. These residues can be dangerous if they are on walkways or patios when they get wet. Call Fosters today.
